bar reconditioning

[wsmobius]

what methods are used to square and refurbish a chainsaw bar??is it better to angle the contact area for less friction?is replacement the best choice if continuing to use old chains?thanks ,mike.

Hi Mike;
Don't put old badly worn chains on a new bar or a new chain on a badly worn bar because you will destroy the better of the two.
If the bottom of the links on the chain are real bad, disgard the chain.
The bar can be dressed and made square again by using a Pferd bar dressing tool.
The rails can be closed by using a bar rail closing tool.
Less friction is obtained by using more bar/chain lube, keep the bar rails square.

Check out this web page they have all the bar recondition stuff you need and I think they will explain how they work and how to go about it! www.madsens1.com  I have a rail squeezer and as far as the burs on the bars we have always taken a flat file to them and did just fine with that!

Preston, thanks for mentioning the burr.
I remove it with a file also then true the bar with the bar dresser.

Hey Kevin how good does that bar dresser work! I've been meaning to ask dan at madsens about 1

[Kevin]

It works really well.
I try to keep proper chain tension, sharp chains and lots of bar/chain lube which reduces wear on the bar but the dresser is a valuable tool to have.
Just make sure you keep the two sections held tight together or the file will fall out of it.

Thanks for the info. Kevin

Kevin,
 I too had the same thing happen,(files fall out if not squeezed),
Lately I have been using an old table mounted round grinder. It was originally meant for woodworking and I just changed the grit of sand paper on it. Its alot cheaper than buying a bar dressing machine and gives the same effect.
It has a good flat working surface wich allow me to either lay the bar down or stand it up.
